GTA is my favorite by far but there's fallout 3,Boarderlands is coming out. Some of the Pros to these type of games are exploring the whole land or city,being able to see all the artwork that's put in to the areas. The interaction that goes with an entire city of AI. Wondering aimlessly for hours doing nothing at. Cons:Wondering aimlessly for hours doing nothing at.

Fable 2 is pretty detailed in what you can do, I personally didn't care too much for the game itself but that is another one that you can pick the sex of your character and their physical appearance reflects what courses you take and you can dress them in whatever you want.
